NOTES:

1.Values include losses for ®lters, unit casing, and wet coils. See page 52 for accessory/FIOP static pressure information.

2.Extensive motor and electrical testing on these units ensures that the full range of the motor can be utilized with con®dence. Using your fan motors up to the wattage ratings shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected. See Evaporator-Fan Motor Performance table on page 55 for addi- tional information.

3.Use of a ®eld-supplied motor may affect wire sizing. Contact your local representative for details.

*Motor drive range is 835 to 1185 rpm. All other rpms require a ®eld- supplied drive.

NOTES:

1.Boldface indicates ®eld-supplied motor and drive are required.

2.Values include losses for ®lters, unit casing, and wet coils. See page 52 for accessory/FIOP static pressure information.

3.Maximum continuous bhp is 1.0, and the maximum continuous watts are 1000. Extensive motor and electrical testing on these units en- sure that the full range of the motor can be utilized with con®dence. Using your fan motors up to the wattage ratings shown will not result in nuisance tripping or premature motor failure. Unit warranty will not be affected. See Evaporator-Fan Motor Performance table on page 55 for additional information.

4.Use of a ®eld-supplied motor may affect wire sizing. Contact your local representative for details.

5.Interpolation is permissible. Do not extrapolate.
